internal compiler error: in force_decl_die, at dwarf2out.c:19261

The closest bug I could find is about -fenable-icf-debug (Bug 46132) but that
option has been removed.

I usually reduce testcases with delta before submitting them, but g++ got into
an infinite loop apparently. Maybe ulimit would help work around that...
